  4. Tighten fixing bolts of camshaft brackets as follows.
    1. Tighten in the order from 9 to 11 with tightening torque 2.0 N.m (0.2 kg-m, 17 in-lb).
    2. Tighten in the order from 1 to 8 with tightening torque 2.0 N.m (0.2 kg-m, 17 in-lb).
    3. Tighten all bolts in specified order with tightening torque 5.9 N.m (0.6 kg-m, 52 in-lb).
    4. Tighten in the order from 1 to 11 with tightening torque 9.0 to 11.8 N.m (0.92 to 1.2 kg-m, 80 to 104 in-lb).

    CAUTION: After tightening fixing bolts of camshaft brackets, be sure to wipe off excessive sealant from the parts listed below.
    • Mating surface of rocker cover.
    • Mating surface of front cover, when installed without the front cover.
  5. Install camshaft sprockets.
    • Install them by lining up the mating marks on each camshaft sprocket with the ones painted on the timing chain during removal.
    • Before installation of chain tensioner, it is possible to re-match the marks on timing chain with the ones on each sprocket.
